The input can be retreived with a '<>':
my $input = <>; chomp($input);
my ($type, $value) = split(' ', $input);
The '$type' variable will be 'integer', 'string' etc and '$value'
will contain the value you want to set the OID to.
The error 'wrong-type' should work, but maybe not for 'set' commands.

If you check the logfiles for snmpd, you'll notice that snmpd first
tries to do a GET on the OID and _THEN_ do the 'SET'... So what you
got was just the result from the 'GET', not the 'SET'.

Then there's something wrong with the perl script. Either there's an
exit, die or other parse/compile error that makes it die.
Try this:
printf "set\n1.3.6.1.4.1.2021.255.1.1\ni 5\n" | /path/to/pass_persisttest
you SHOULD see some perl compile errors in this...
If you'd like to see a (bad!) example on how to implement SET, GET, GETNEXT and
tables ('normal'/simple tables and linked tables) in a pass_persist perlscript,
have a look at http://www.bayour.com/bacula-snmp/.
The code itself isn't to bad, it's the last part (trying to figure out what
OID comes next) that sucks.
